柚苷酶 naringinase( 柚苷酶β-L-Rhammosidase) 法定编号：EC3.2.1.40 柚苷酶是一种能水解柚苷生成柚配基起到脱苦作用的酶。由β-鼠李糖苷酶和β-葡萄糖苷酶组成。柚苷先经β-鼠李糖苷酶水解为鼠李糖与普鲁宁(prunin，无苦味但有涩味)；后者再由β-葡萄糖苷酶水解成为全部无苦味、涩味的柚配质。常用的柚苷酶生产菌为黑曲霉、米曲霉和青霉属的一些菌种。性状 主要含有两种酶，一种是鼠李糖苷酶，可使苦味的柚苷（柚配质-7-鼠李糖苷）水解成鼠李糖和野樱素，第二种是β葡萄糖苷，它可使野樱素水解成无味的柚配质和葡萄糖，其过程为： 柚苷－－野樱素+鼠李糖——－－柚配质+葡萄糖。
